El problema puede ser relacionado a la configuracion de logstash con respeto a una libreria que escribe en el directorio /tmp > [@Problem with cipher in beat input](https://discuss.elastic.co/t/problem-with-cipher-in-beat-input/67841/5): > > Had this issue with a system, and found the problem was /tmp was mounted with noexec option. Removing the noexec option and rebooting fixed the issue on my system. It looks like logstash puts a copy of the libnetty-tcnative dynamic library so in /tmp and tries to load it from there which the noexec option blocks. Loading code from /tmp seems like a security risks. EDIT: the code putting the library in TMP is in netty which is used by logstash. EDIT 2: maybe the tmp path can be made more sa… puedes cambiar en el jvm.options de logstash el parametro `-Dio.netty.native.workdir=/directorio` donde `directorio` debe ser un directorio diferente a tmp --- _[View the full topic](https://discuss.elastic.co/t/error-logstash-requires-the-configuration-of-certificate-authorities/125218)._
